Professional GIS Data Converters for Every Format – KML, GeoJSON, GPX, SHP, NAD83 & More
Working with geographic data means juggling many file formats. GeoJSON is perfect for web maps and JavaScript applications, KML and KMZ power Google Earth visualizations, GPX stores GPS tracks from handheld devices and fitness watches, while SHP (Shapefile) remains the industry standard for GIS desktop software like QGIS and ArcGIS. Our free online GIS tools bridge these formats instantly.
Need to transform coordinate systems? Convert ECEF XYZ coordinates to latitude/longitude altitude, switch between UTM easting/northing and WGS84, decode MGRS military grid references, or translate NAD83 to WGS84 datum for accurate US surveying. We also support modern location encodings like Plus Codes (Open Location Code) and Geohash for compact sharing.
All tools are built for performance – lightweight, mobile-friendly, with lazy loading and no file uploads to external servers. Whether you are a surveyor converting acre to hectare, a developer parsing KML to CSV, or a hiker turning GPX to KML, you get instant results with preserved elevation, time stamps and attributes. No registration, no watermarks, 100% free for personal and commercial GIS workflows.
100% Secure & Private
All processing happens in your browser. Your KML, GeoJSON or SHP files never touch our servers. GDPR compliant and safe for sensitive data.
Lightning Fast Conversion
Optimized JavaScript engine converts large GeoJSON, KMZ or SHP files in milliseconds. Lazy loading, no bloat, works even on slow mobile networks.
Survey-Grade Accuracy
Uses WGS84 ellipsoid, official NAD83 to WGS84 shift grids, UTM zone auto-detection and precise ECEF transformations for professional results.

FAQs – GIS Tools
How to convert GeoJSON to KML online free?
Upload your .geojson file to our GeoJSON to KML converter. The tool reads features, properties, Points, LineStrings and Polygons and exports a standards-compliant KML ready for Google Earth. Works with large files, preserves attributes as ExtendedData.
What is difference between NAD83 and WGS84 datum conversion?
NAD83 is fixed to North American tectonic plate for US surveying, while WGS84 is global GPS datum. They diverge by up to 2 meters. Our NAD83 to WGS84 converter applies 7-parameter Helmert transformation so your coordinates align perfectly in Google Maps and GNSS devices.
How to convert GPX to KML for Google Earth?
GPX tracks from Garmin, Strava or handheld GPS can be visualized in Google Earth as KML. Just use our GPX to KML tool, upload GPX, and download KML with elevation, timestamps and styles intact. No installation needed.
